;; 1. 定义智能体种类（Breeds）
;; ======================================================================
breed [
  traditional-women  ;; “传统性别观念女性”的集合（多只 turtle）
  traditional-woman  ;; 单个“传统性别观念女性”的称呼（单数）
]
breed [
  new-women          ;; “新兴性别观念女性”的集合
  new-woman          ;; 单个“新兴性别观念女性”的称呼
]
breed [
  fertility-info     ;; “生育信息”（风险/收益）的集合
  info               ;; 单条“生育信息”的称呼
]

;; ======================================================================
;; 2. 定义各类智能体的特有变量
;; ======================================================================
traditional-women-own [
  anxiety    ;; 生育焦虑值（数值越大表示越焦虑）
  intention  ;; 生育意愿值（数值越大表示越愿意生育）
]
new-women-own [
  anxiety    ;; 同上，专门给新兴性别观念女性
  intention
]
fertility-info-own [
  quant      ;; 信息热度（影响“推送概率”和“存活时长”）
]

;; ======================================================================
;; 3. 初始化模型（setup 过程）
;; ======================================================================
to setup
  ca                                          ;; 清空所有 turtles、patches、links 及变量

  ;; 3.1 创建 num-traditional-women 只“传统女性”
  create-traditional-women num-traditional-women [
    set color yellow                          ;; 将她们标为黄色（代表未表达立场）
    set size 2                                ;; 大小设为2，便于观察
    set shape "person service"                ;; 形状选择“person service”
    setxy random-xcor random-ycor             ;; 在世界范围内随机分布位置
    set anxiety 0                             ;; 初始生育焦虑设为0
    set intention 0                           ;; 初始生育意愿设为0
    set heading random 360                    ;; 随机朝向0~359度
  ]

  ;; 3.2 创建 num-new-women 只“新兴女性”
  create-new-women num-new-women [
    set color yellow
    set size 2
    set shape "person graduate"               ;; 形状选择“person graduate”
    setxy random-xcor random-ycor
    set anxiety 0
    set intention 0
    set heading random 360
  ]

  ;; 3.3 创建 num-info 条“生育信息” （红色风险 vs 绿色收益）
  create-fertility-info num-info [
    ;; info-ratio：0~10之间的阈值，控制红/绿信息生成比例
    ;; 若 random 10（0~9 随机整数） >= info-ratio，则判为风险信息
    ifelse random 10 >= info-ratio [
      set color red                           ;; 红色表示风险
    ] [
      set color green                         ;; 绿色表示收益
    ]
    setxy random-xcor random-ycor             ;; 随机分布信息
    set shape "circle"                         ;; 信息以圆点呈现
    set size 0.5                               ;; 大小为0.5
    ;; quant 取值：10 + random 20 ，即在 [10,29] 的均匀整数
    set quant 10 + random 20
    set heading random 360                     ;; 随机朝向，用于信息扩散
  ]

  reset-ticks                                 ;; 重置时钟，从 0 开始计数
end

;; ======================================================================
;; 4. 主循环（go 过程）
;; ======================================================================
to go
  ;; 4.1 让所有传统女性移动并使用社交媒体
  ask traditional-women [
    fd 1                                      ;; 向前移动 1 步
    media-use1                                ;; 调用“传统女性”社交媒体使用逻辑
    form-extreme-intention                    ;; 检测是否形成极端低意愿（< -100）
  ]

  ;; 4.2 让所有新兴女性移动并使用社交媒体
  ask new-women [
    fd 1
    media-use2                                ;; 调用“新兴女性”社交媒体使用逻辑
    form-extreme-intention
  ]

  ;; 4.3 若开启“选择性接触”机制，则再执行一次各自的选择性接触逻辑
  if selective-exposure? [
    ask traditional-women [
      fd 1
      selective-exposure1
    ]
  ]
  if selective-exposure? [
    ask new-women [
      fd 1
      selective-exposure2
    ]
  ]

  ;; 4.4 若开启“社会支持”机制，则各自形成支持社区并相互影响
  if social-support? [
    ask traditional-women [
      social-support1
    ]
  ]
  if social-support? [
    ask new-women [
      social-support2
    ]
  ]

  tick                                       ;; 时钟前进一步
end

;; ======================================================================
;; 5. 传统女性的“社交媒体使用”逻辑（media-use1）
;;    ——根据视野内风险/收益信息数量决定焦虑和意愿的变化，并“推送”相似信息
;; ======================================================================
to media-use1
  ;; 5.1 在以 vision 为半径的圈内统计红色（风险）与绿色（收益）信息数量
  let risk-info   count fertility-info with [color = red]   in-radius vision
  let profit-info count fertility-info with [color = green] in-radius vision

  ;; 5.2 若风险信息占优（risk-info > profit-info 且 risk-info > 0）
  if risk-info > profit-info and risk-info > 0 [
    ;; 5.2.1 传统女性自身焦虑+1，意愿−1
    ask self [
      set anxiety   anxiety + 1
      set intention intention - 1
    ]
    ;; 5.2.2 算法推送：选取视野内一条风险信息，使其热度+2，并繁殖一条新信息
    ask one-of fertility-info with [color = red] in-radius vision [
      set quant quant + 2
      hatch 1 [
        set color red                          ;; 新繁殖的信息也标为红色风险
        ;; 这里 hatch 后的新 info 继承 quant, heading 等属性，可继续传播
      ]
    ]
  ]

  ;; 5.3 若收益信息占优（profit-info > risk-info 且 profit-info > 0）
  if profit-info > risk-info and profit-info > 0 [
    ask self [
      set anxiety   anxiety - 2              ;; 收益信息降低焦虑 2 单位
      set intention intention + 2            ;; 收益信息提高意愿 2 单位
    ]
    ask one-of fertility-info with [color = green] in-radius vision [
      set quant quant + 2
      hatch 1 [
        set color green                       ;; 推送收益信息
      ]
    ]
  ]
end

;; ======================================================================
;; 6. 新兴女性的“社交媒体使用”逻辑（media-use2）
;;    ——与传统女性相似，但参数量级不同，体现“新兴群体”对信息的敏感度差异
;; ======================================================================
to media-use2
  let risk-info   count fertility-info with [color = red]   in-radius vision
  let profit-info count fertility-info with [color = green] in-radius vision

  if risk-info > profit-info and risk-info > 0 [
    ask self [
      set anxiety   anxiety + 2              ;; 焦虑增幅更大（+2）
      set intention intention - 2            ;; 意愿降幅更大（-2）
    ]
    ;; 推送一条风险信息（n-of 1 保证只推一条）
    ask n-of 1 fertility-info with [color = red] in-radius vision [
      set quant quant + 2
      hatch 1 [
        set color red
      ]
    ]
  ]

  ;; 6.2 收益主导
  if profit-info > risk-info and profit-info > 0 [
    ask self [
      set anxiety   anxiety - 1              ;; 焦虑降幅较小（-1）
      set intention intention + 1            ;; 意愿升幅较小（+1）
    ]
    ask n-of 1 fertility-info with [color = green] in-radius vision [
      set quant quant + 2
      hatch 1 [
        set color green
      ]
    ]
  ]
end

;; ======================================================================
;; 7. 传统女性的“选择性接触”逻辑（selective-exposure1）
;;    ——主动回避或靠近信息，并继续传递偏好的信息类型
;; ======================================================================
to selective-exposure1
  let risk-info   fertility-info with [color = red]   in-radius vision
  let profit-info fertility-info with [color = green] in-radius vision

      setxy random-xcor random-ycor          ;; 跳到新随机位置
      fd 1

  if any? profit-info [
    ask self [
      ;; 将朝向设为所有收益信息中心的平均 heading
      set heading mean [heading] of profit-info
